Peripheral Control functions

This section provides functions allowing to:
Compute the 32-bit CRC value of 32-bit data buffer, using combination of the previous
CRC value and the new one.
Compute the 32-bit CRC value of 32-bit data buffer, independently of the previous
CRC value.
This section contains the following APIs:
HAL_CRC_Accumulate()
HAL_CRC_Calculate()
10.2.4

Peripheral State functions

This subsection permits to get in run-time the status of the peripheral and the data flow.
This section contains the following APIs:
HAL_CRC_GetState()
